I went to a workshop for psychologists once. Taught by a professor from Harvard who wrote at least two books on the subject. It was interesting. I got 6 continuing credits for taking it. Just the thing to keep my psychologist's license current. But I have (and had) no such license, since I took only Psych 101 and Psych 102 in college about 50 years ago, and none since. But they gave the credits to anyone who took the course, and it never occurred to the administrators that a non-professional would take it. ;-) ======================================I've often taken continuing ed. tax courses through the UW law school. And they know that quite a few of their participants are accountants.
